Definitions
- the invention relates to an outer basket of the centrifuge basket of a sieve centrifuge, wherein in the basket basket sieve segments are conically fastened, the basket has a plurality of concentric support rings with rectangular cross-section with greater width than thickness and the annular broad sides are parallel to each other and at right angles to the basket axis.
- the object of the invention is to improve the basket of a centrifuge such that with simple design, installation, easy replaceability and low wear the largest possible effective screen surface remains free.
- the parallel to the basket axis rods allow a particularly simple structural design with ease of manufacture and assembly.
- the bars cover not the outside of the screen surface, so that the screen surface rests with its outer side only on the narrow sides or inner edges of the support rings.
- the simple disassembly is also an easy replacement of items in particular the wearing parts given.
- a particularly simple assembly and disassembly is given when the first and / or last support ring releasably secured to the rods is in particular screwed.
- the sleeves may be made of metal and have an outer ceramic layer, so that the rods are securely protected against wear.
- this may be the sleeves of metal and the outside of a sleeve of resistant material in particular be surrounded by ceramic.
- the support rings have a substantially identical outer diameter and an inner diameter decreasing towards a basket end.
- FIG. 1 is a perspective view of a centrifuge basket with constant outside diameter
- FIG. 2 shows the centrifuge basket according to FIG. 1 in a side view
- 3 shows the centrifuge basket according to FIG. 1 in the axial section BB
- FIG. 3 shows the centrifuge basket according to FIG. 1 in the axial section BB
- FIG. 5 is a perspective view of a second embodiment of a centrifuge basket with a gradation
- FIG. 6 shows the centrifuge basket according to FIG. 5 in a side view
- FIG. 7 shows the centrifuge basket according to FIG. 5 in the axial section B-B, FIG.
- the carrying basket 1 of a centrifuge basket has a plurality of coaxial supporting rings 2 made of sheet metal, on which not shown inside sieve segments and the annular broad sides 2a, 2b to those of the other support rings parallel and perpendicular to the basket axis. 3 are arranged so that basket radii lie in the planes of the annular broad sides 2a, 2b.
- the support rings 2 thus have parallel to the basket axis a small height or thickness D and in the radial direction a ring width B, which is a multiple of the thickness D.
- These axially flat support rings 2 are arranged at regular intervals preferably equal to A over the axial length of the carrier basket, wherein the tapered end of the conical screen toward the ring width B of the support rings 2 increases and / or the inner diameter decreases, so that the support rings 2 a conical Form inner shape for external support of the screen or Siebbelages.
- metal sleeves 6 as a spacer is omitted in a non-illustrated embodiment, when the support rings 2 are secured to the guided through them bars 4 against displacement. This is done by threaded nuts on the rods 4, by pin connections by welding 10 and / or by projections on the rods. In these cases, the metal sleeves 6 are omitted and replaced by ceramic sleeves of the same height H.
- At least one end or both ends of the metal rods 4 have an external thread on which a threaded nut 8 is screwed to hold the outermost support ring 2, respectively. This supports easy assembly and disassembly.
- FIGS. 6 to 9 differs from the previous only in that not all support rings 2 have the same outer diameter, but the closer the tapered end support rings have a smaller outer diameter.
- further holding rods 4 are inserted through the support rings 2 of the reduced basket area, which have a smaller radial distance from the basket axis 3 than the other holding rods.
- a transition ring forming the transition to the reduced area 2c thus has holes for the bars 4 of both basket areas.
